前台运行PUT时出现错误：jquery.min.js?v=2.1.4:4 Uncaught TypeError: (b.contentType || "").indexOf is not a function；
最后检查少了
原代码：
$.ajax({
type: ‘PUT‘,
data: JSON.stringify(addData),
contentType:"application/json",
url: addr + "/information/update",
contentType: function () {
layerDialog = layer.msg(‘正在修改...‘,{
icon: 16, shade:0.5
});
html = "";
},
----------
改后代码：
type: ‘PUT‘,
data: JSON.stringify(addData),
contentType:"application/json",
url: addr + "/information/update",
beforeSend: function () {
layerDialog = layer.msg(‘正在修改...‘,{
icon: 16, shade:0.5
});
html = "";
},
----------------
